Heliopan
Filter Coatings.
Heliopan filters have a lifetime warranty.
Heliopan glass filters are made exclusively with glass from Schott (Zeiss) the world's
finest optical
glass supplier. Heliopan filters are "dyed in the mass" and ground, polished and
coated to the highest standards of the German optical industry. All Heliopan screw in type
and series size filters are mounted in precision black anodized brass rings to eliminate
binding or cross threading and to ensure optimal alignment. The care, quality and
performance of Heliopan's filters make them simply the world's finest filters!
Heliopan Standard Coated Filters
Each Heliopan filter has an anti reflective coating, scratch proof metallic oxide
coating on each surface. This Special hard coating reduces reflections by approximately
50%. Heliopan filters are referred to as double coated. This means that the front
and rear glass surfaces have coating applied to them.
Heliopan SH-MC Multi Coated Filters.
On special order Heliopan can supply most popular filters with a special multi
coating. The SH-MC (Super High- Tech Multi Coating) consists of 7 layers of coating on
each side of the glass. Reduces reflections in the visible area of the spectrum to a
minimum. Please allow 6 to 8 weeks for delivery on special order Heliopan.
Most special effect filters such as soft focus, cross, fog and Softars are
not coated.
